Abstract

Surface runoff from upland areas in northern Scotland can be excessively coloured and turbid, making water treatment costs high. In contrast, groundwater has little colour or suspended solids, and has a more stable water quality, therefore treatment needs can be minimal. A number of public water supply schemes based on the development of groundwater in alluvial and glacial deposits are reviewed. These supplies range from major projects such as the 27 M1/d Spey and 10 Ml/d Fort William schemes to the 0.16 M1/d supply for Dalwhinnie. It has been demonstrated that yields of up to 2 M1/d can be achieved from dug wells or boreholes even where the aquifer thickness is limited. Larger yields have been obtained from infiltration galleries and Ranney wells. Future challenges include improved siting techniques to locate thicker and more productive sediments and the avoidance of groundwater containing high iron and/or manganese concentrations.
